#!/usr/bin/env python

staff_list = 'user.txt'

f = open(staff_list)

c = f.readlines()

while True:

  user_input = raw_input('33[32;1mPls input sth to search:33[0m ').strip()

  if len(user_input) == 0: continue

  for line in c:

    if user_input in line:

      print line

      break

  else:

    print '33[31;1mnot a vaild input!33[0m' 

解决1次只匹配单行的问题,增加一个key,作为信号量,当匹配时则为key赋值为1,否则为0.
